We are having a problem with the email notifications not being sent out.

We have recently integrated our servers with our head office, and have moved from our old exchange server to a new exchange 2003 server.

Since the change, we are unable to get the email notification working.

We updated the registry settings for Aardvark and rebooted the server. Everything else seems to be working correctly.

The service is running as an administrator on the local machine.

There are no .xml files in the root of the folder called 'New Queue'. There is a sent and failed folder within this containing many .xml files. The .xml files in the failed folder appear to be the current email notifications.
Where would the errors be logged if the problem was here?

The is no queued mail on the exchange server, and no logs of any activity from the Aardvark account.

We have checked the exchange server to make sure it has the option to allow mail relay.

More than likely the issue is that the new Exchange Server does not allow mail relay from the Aardvark server, which is the default, and very sensible setting. You should get the Exchange Server admin to allow relay from the IP address of the Aardvark Server. There are other potential configuration issues, such as the SMTP server requiring authentication.

The Exchange server itself may also reveal the reason why you cannot send mail. If you open a command prompt on the Aardvark server, then run ‘telnet <name of exchange server> 25’. This will allow you to run SMTP commands on the Exchange Server. If the connection is successful, try sending a test message using these commands:

I have confirmation from our IT department that Mail relay is allowed and authentication is not required.

I tried to Telnet the server as per your instructions. The connection is made with the server, but when I type the MAIL FROM: command, I get an error stating "client does not have permission to submit mail to this server".

Do you have any more suggestions as to what could be causing the problem?

You appear to right about that. I got them to show me, and they have the basic authentication and integrated windows authentication boxes checked.

I have also been informed that I will not be allowed to change the server configuration by allowing anonymous access.

Is there a work around we can use here?

I was also looking at creating an external pop3 email account, but they all seem to require authentication for outgoing mail. I don't mind using this instead of our exchange server, providing there is a way we can get around this?
